It’s no surprise that the former Beatle is one of the world’s richest musicians. Even after a costly divorce, Sir Paul’s net worth is estimated at $660 million.

Being a member of The Beatles, who have sold over 170 million albums in the United States alone, doesn’t hurt either. (Photo by Roberto Serra/Iguana Press/Getty Images)
